HANDLE-BAR CLAMP FOR BICYCLES.

SPECIFICATION forming part of Letters Patent No. 596,341, dated December 28, I897.

To all whom it may concern.-

Be itknown that 1, CHARLES E. SEYMOUR, of New Haven, in the county of New Haven and State ,of Connecticut, have invented a new Improvement in Handle-Bar Clamps for Bicycles; and I dohereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, aview in side elevation of a handle-bar clamp constructed in accordance with my invention; Fig. 2, a view thereof in side elevation; Fig. 3, a view in vertical longitudinal section; Fig. 4, a view in vertical transverse section; Fig. 5, a detached view, in side elevation, of the head; Fig. 6, a detached perspective view of the clip; Fig. 7, a detached view, in side elevation, of the nut.

My invention relates to an improvement in handle-bar clamps for bicycles, the object being to produce a simple, compact, conveniently-operated, and effective clamp, composed of few parts, and presenting an elegant and workmanlike appearance.

With these ends in view my invention consists in a handle-bar clamp having certain details of construction and combinations of parts, as will be hereinafter described, and pointed out in the claim.

In carrying out my invention as herein shown I employ a head comprising a horizontally-arranged oblong bearingA, an annular vertical shoulder A, located directly bebelow the said shoulder and smaller in diameter than the same and adapted to be inserted into the open upper end of a tubular handle-bar post of any approved construction. The said bearing is formed in its upper face with a longitudinal concave and nearly semicircular seat A struck on a circle by preference a trifle larger than the circle of the handle-bar in transverse section. The said head is constructed, as shown, with a centrally-arranged vertical opening A, which passes downwardly through the bearing A, the shoulder A, and the shank A As herein shown, I have inserted into the upper end of the said opening a metal cup B, the edges of ranged correspondin g do wnwardly-proj ectin g retaining-arms C C, the outer faces of the lower ends of which are furnished with sectional screw-threads C C as very clearly shown in Figs. 4 and 6. These arms, it is to be noted, lie practically in the planes of the edges of the clip proper and form extensions of such edges. For the reception of these arms the opposite faces of the bearing A and shoulder A are constructed with corresponding vertical grooves A A which receive the arms, so that the outer faces of the same are flush with the outer face of the bearing and shoulder. The threaded lower ends of the arms are engaged by a nut D, mounted upon the shoulder A and having rotary as well as vertical movement thereupon, the upper face of the nut bearing. against the shoulder a, formed between the head and the annular shoulder A. I would call particular attention to the fact that although the arms C C are,

' as shown, inclined veryslightly toward each other their lower ends are practically separated bya distance corresponding to the diameter of the bar to be clamped, so that neither the arms of the clip nor the clip have to be sprung and separated in applying it to or removing it from the handle-bar head, whereby my improved device is rendered very convenient for use. It will be understood, of course, that after the clip is set down over the handle-bar and head it may be drawn downward, so as to clamp the bar very firmly in place, by means of the nut D, which takes the place of the bolts heretofore generally employed.

It is apparent that in carrying out my invention some changes from the construction herein shown and described may be made. Thus I may dispense with the cup B and employ some other means for preventing the handle from rotating in the clamp. I would therefore have it understood that I do not limit myself to the exact construction shown, but hold myself at liberty to make such variations therefrom as fairly fall Within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In ahandle-bar clamp for bicycles, the combination with a head comprising a horizontally-arranged concave seat for the reception of the handlebar, a vertical shoulder located below the seat, and a shank located below the said shoulder and adapting the head to be secured to a handle-bar post, and the said head being formed with two centrally-arranged oppositely-located vertical grooves; of a bowed strap-like clip substantially semicircular in ing witnesses.
